Despite being faster than an $880 Dual-Core AMD processor, the $520 Athlon64 X2 4400+ is still very expensive. Compare this to the $250 you will pay to own an Intel Pentium D 820 processor and the bang for your buck factor of the AMD processor looks very bleak. Of course there is the Athlon64 X2 3800+ which retails for $350 US but its just not going to deliver what the 4400+ can on the overclocking front. The lower clock multiplier dulls the processor right down, as does the L2 Cache which is cut in half. Then at the end of the day you are still paying $100 US more for a processor that’s physically no faster.
